1981 45th Birthday Gift. 1981 was a low mintage year for the 50p, making these cufflinks very rare. The Irish 50p Cufflinks were made as there were no other coins made that year. This makes them a very distinctive set of cufflinks. The 50p was a seven-sided coin and featured the woodcock design. The coins are encased into the cufflinks and would be suitable for someone who wants something just a little bit different.
